Trigon

The living embodiment of evil itself, Trigon has tried numerous times to conquer reality, but has been thwarted by his daughter Raven and the Teen Titans.

Born from the unholy union between evil cast out of human souls and the mystical energy of the realm of Azarath, Trigon is the physical manifestation of the darkness that lurks in the worst parts of humanity. A tyrant and a monster, Trigon rules over hundreds of worlds from his home in Azarath, but is always looking for more to conquer. 

Over the years, the demon lord has spawned a number of children to use as weapons in his endless thirst for domination. Fortunately, at least one of those offspring—the DC superhero Raven—has other ideas about her destiny.
